`Our invention relates to coordinatedfbrakf ing and,clutchingVapparatusdesigned .par-` ticularly for sandreels, but adapted tobeusedin other types of apparatus.

One object of this invention 1s to provide s means Wherebyeither thebrake may be set and the clutch releasech'or theclutch maybe interlockedwith its companionA member Vand thelbrake released, thestructure'being vsuch ,thatfthe lopening movementy of the clutchmay stop Without a'ectingtliebraking operation.` :In the lapparatus shownthe vrmovement of theclutch actuating'- member 1 isveryl small, and it,A is lquite importantthat fflthe brakesetting `meansf'shallv have further possible movementafter the clutch has been f opened. This Vgives more reedomyinthe designof the apparatus and allows the brake operating devices to compensatefor Wear, of the brake linings-and drums.` Other objects appearhereinafter..- Y A g Referring; to the accompanying drawing, Y Figa lisaside view, partly in vertical vsec- .Y tion, of a clutch` and brakemechanism containing vour invention,parts being broken away atbothends;Fig. 2, a section onfthe .lineII-IIon Fig. 1; Fig. A3,afragmentary clutchfactuating V sleeve on the main shaft, parts beinginsection; and Fig.l 4, an edge view of th,e' ,cam v 38.
